floating point precision.</p>
<p>A QLineF describes a finite length line (or line segment) on a
two-dimensional surface. QLineF defines the start and end points of
the line using floating point accuracy for coordinates. Use the
<a href="qlinef.html#toLine">toLine</a>() function to retrieve an
integer based copy of this line.</p>
<table class="generic">
<tr class="odd" valign="top">
<td><img src="images/qline-point.png" /></td>
<td><img src="images/qline-coordinates.png" /></td>
</tr>
</table>
<p>The positions of the line's start and end points can be
retrieved using the <a href="qlinef.html#p1">p1</a>(), <a href="qlinef.html#x1">x1</a>(), <a href="qlinef.html#y1">y1</a>(),
<a href="qlinef.html#p2">p2</a>(), <a href="qlinef.html#x2">x2</a>(), and <a href="qlinef.html#y2">y2</a>()
functions. The <a href="qlinef.html#dx">dx</a>() and <a href="qlinef.html#dy">dy</a>() functions return the horizontal and
vertical components of the line, respectively.</p>
<p>The line's length can be retrieved using the <a href="qlinef.html#length">length</a>() function, and altered using the
<a href="qlinef.html#setLength">setLength</a>() function.
Similarly, <a href="qlinef.html#angle">angle</a>() and <a href="qlinef.html#setAngle">setAngle</a>() are respectively used for
retrieving and altering the angle of the line. Use the <a href="qlinef.html#isNull">isNull</a>() function to determine whether the
QLineF represents a valid line or a null line.</p>
<p>The <a href="qlinef.html#intersect">intersect</a>() function
determines the <a href="qlinef.html#IntersectType-enum">IntersectType</a> for this line
and a given line, while the <a href="qlinef.html#angle">angle</a>()
function returns the angle between the lines. In addition, the
<a href="qlinef.html#unitVector">unitVector</a>() function returns
a line that has the same starting point as this line, but with a
length of only 1, while the <a href="qlinef.html#normalVector">normalVector</a>() function returns a
line that is perpendicular to this line with the same starting
point and length.</p>
<p>Finally, the line can be translated a given offset using the
<a href="qlinef.html#translate">translate</a>() function, and can
be traversed using the <a href="qlinef.html#pointAt">pointAt</a>()
function.</p>
